In it, Francis went further than previous comments criticizing the global economic system, attacking the “idolatry of money” and beseeching politicians to guarantee all citizens “dignified work, education and healthcare”.

He also called on rich people to share their wealth. “Just as the commandment ‘Thou shalt not kill’ sets a clear limit in order to safeguard the value of human life, today we also have to say ‘thou shalt not’ to an economy of exclusion and inequality. Such an economy kills,” Francis wrote in the document issued on Tuesday.

“How can it be that it is not a news item when an elderly homeless person dies of exposure, but it is news when the stock market loses 2 points?”

The pope said renewal of the Church could not be put off and said the Vatican and its entrenched hierarchy “also need to hear the call to pastoral conversion”.
